BRACKET.

Application filed October 2,

To all whom it may concern Be it known that I, ARTHUR WV. BROW'NE, acitizen of the United States, and a resident of Prince Bay, in thecounty of Richmond, State of New York, have invented certain new anduseful Improvements in Brackets, of which the following is aspecification.

My invention relates to wall brackets which are designed and intended tosupp rt electric motors and it has particular -refer ence to the meansprovided in connection with such brackets for supporting the conductorfor supplying electricity to said motor to operate it.

I have shown my invention as applied to. a construction of bracketpreviously invent-' ed by me and illustrated and .described in, LettersPatent of the United States No. 918,276, granted April 13, 1909 to myassignee. In the said patent members of the main section and fore-armsection of which the bracket consists are hollow and the electricconductor is threaded therethrough and is supported thereby. It has beenfound to be a dii'licult task to thread the conductor through saidhollow members; and also in order to thread the conductor through thesaid members it is necessary to disconnect the same either from themotor or from the junction box or other part or parts to which it isconnected. The disconnected end of the conductor is then inserted intoone of the "hollow members and threaded there- 'through and is theninserted into the other of said hollow members and in like mannerthreaded through it. This operation otdisconnecting the conductor andthreading the same through the said hollow members, as stated, entailsconsiderable work and trouble and the loss of a great deal of time.

The object of my present invention is to obviate such work and troubleand loss of time by so constructing a member or members of the bracketthat the conductor may be quickly and readily secured thereto withoutthe, necessity of threading the same through a hollow member ormembers-thereof and therefore without disconnecting the same either fromthe motor or from other object or part to which it may be con- 1 nected.

Although I have as employed in connection with a brackcti such as isillustrated and described in Letillustrated my invention Specificationof Le'tters'latent.

Patented Oct. 14., 1913,

1911'. Serial No. 652,271.

ters Patent No. 918,276, it should be understood that the same may beembodied in other and dilterent forms and constructions of brackets.

In the accompanying drawing I have illustrated one embodiment of myinvention in which channels are provided in members or parts of thebracket, the walls of which channels are undercut so that the edges ofthe said channels are nearer together than the sides of the lntermedlateport-ions thereof. It will be understood that changes 1n the details ofconstruction may be made within the scope of the claims withoutdeparting from my invention.

In the drawing: Figurel is a side elevation of a bracket embodying myinvention; TI is a side elevation of one of the parts employed in theconstruction thereof; and Fig. III is a view taken on the line III-IIIof Fig. TI and showing a portion of the part in said figure inperspective.

In the drawing, a dental bracket is illustrated and it -consists of amain section 1 and a forearm section 2 each section being composed oftwo parallel members 3 and 4, and 5 and ('3 respectively. The members 3and d are pivotally connected at 7 and 8 to a bracket member 9 havinghorizontal turning connection with a stationary plate 10 secured to awall or other suitable support.

A pintle 11 serves to connect the bracket member 9 to the stationaryplate 10. The outer ends of the members 3 and i are respectivelypivotally connected at 12 and 13 to a connecting plate or plates 14-.There are in the construction illustrated two of said plates, only oneof which, however, is shown. The members 5 and 6 of the forearm sectionare pivoted at their inner ends at 12 and '15 to the said plate orplates 14.

It will be observed that the inner end of the member 5 is connected tothe same pivot as the outer end of the member '3. The members 5 and 6are pivoted at 16 and 17 to an end piece or connecting member 18 whichnot only serves as a means for connecting the outer ends of the saidmembers 5 and 6 together but also as a means for supporting an electricdental engine motor 19, the flexible shaft 20 and hand piece 21 carriedthereby.

For the purpose ofcausing the sections 1 and 2 of the bracket to move inunison to- Ward and away from each other and maintain correspondmgangular relations wlth respect to a vertical plane drawn centrallybetween said sections, the outer end of the member 4 is provided with aprojection or extension 22 which is connected by means of a link 23 to aprojection or extension 24 of the inner end of the member 5 of theforearm section 2.

As thus far described the construction is the same or substantially thesame as that illustrated in the said Patent No. 918,276.

My invention consists in the provision of a channel or channels in thebracket or a member or members thereof for the reception and support ofan electric conductor. In the construction shown the channel or channelsare provided in the members 4 and 6 and are indicated by the referencenumbers 25 and 26. The main port-ions of these channels preferably arecircular, as indicated at 27 in Fig. III of the drawings. The outeredges 28 of the walls of the said channels are nearer to each other thanthe distance bet-ween the opposite sides of the central portionsthereof. In other words, the opposite sides of the said channels-areundercut so that when a conductor, such as 29, the diameter of which issubstantially equal to the greatest diameter of the said channels, ispushed or forced into the said channels through the mouths thereof, thesaid conductor is firmly held in position. It will be observed that thesaid channels extend substantially from end to end of the members 4 and6. The member 4 is provided with notches 30 at the opposite ends of thechannels 25 through which the conductor 29 passes from said channel. Themember 6 is provided with a notch 31 at its inner end through which theconductor 29 leaves the channel 26 and said member is also providedadjacent to its outer end with a notch 32.

33 indicates an overhanging portion of the member 6 beyond the notch 32under which the conductor 29 at a point near its outer end is located.

The continuation of the groove 26 in the direction of the length of themember 6 underneath the overhanging portion 33 ohviates the necessityofa more or less sharp bend in the conductor 29 at a point adjacent to themotor 19, thereby enhancing the neatness in appearance and alsoproviding an additional security for preventing accidental disconnectionof the outer port-ion of the said conductor from the channel 26.

In connecting and securing the conductor to the bracket it is pushedinto the channels 25 and 26 through the mouths thereof and is placed orpositioned in the notches 30 and 31, and in order to place the sameunderneath the overhanging portion 33 it is first placed in the notch 33and is then slid laterally under such portion.

The portion of the conductor intermediate the notch 31 at the inner endof the member 6 and the notch 30 at the outer end of the member 4 islocated between the lower curved edges of the connecting plates 14 andis substantially concealed by them and is also prevented from beingengaged by external objects and thereby possibly dislocated partially orwholly from the grooves 25 and 26.

Having thus described my invention, I claim 1. An adjustable wallbracket for supporting an electric motor and including, in combination,a wall plate, a main section composed of parallel members pivoted tosaid wall plate, and a forearm section composed of parallel members, thesaid sections being pivotally connected to each other and one of themembers of each of the said sections being provided with a longitudinalchannel having a continuously open side for the reception and support ofan electric conductor, the said channel at its point of greatest widthbeing substantially equal to the diameter of the said conductor and themouth of the said channel being of less width. 7

2. An adjustable wall bracket including, in combination, a wall plate, amain section composed of parallel members pivoted to said wall plate anda forearm section adapted to support an electric motor at its outerextremity, each of the said sections or a part thereof being providedwith a channel the mouth of which is narrower than the main portionthereof, and the outer end of the forearm part being provided with aportion which overhangs the outer end of the channel in said part. 7

3. An adjustable wall bracket including, in combination, a wall plate, amain section pivoted to said wall plate, and a forearm section the innerend of which is pivoted to the outer end of the said main section andwhich is adapted to support an electric motor at its outer extremity,each of the said sections or a member thereof being provided with achannel the walls of which are undercut and the said sections or membersthereof, having notches in their sides which communicate with the saidchannels, which channels are adapted to receive an electric conductor.

4. A bracket for supporting a motor, which bracket is provided with alongitudinal channel in one of its sides adapted to receive and supportan electric conductor which, conductor is retained in position in saidchannel by its side walls and the side of said channel being open fromend to end whereby the conductor may be inserted laterally therein atany point without disconnecting the same from the motor or other part towhich it may be connected.

5. An adjustable wall bracket for supporting the electric motor of adent-a1 engine, including in combination a wall plate, a main sectioncomposed of parallel members pivoted to said wall plate, and a forearmsection also composed of a similar number of parallel members, saidsections being pivotally connected, the lower member of each sectionbeing provided with a longitudinal channel having a continuously openside for the reception and support of an electric conductor, the openingin the side of said channel being of a width less than the greatestwidth of said channel and less than the diameter of said electricconductor, the proximate ends of each of said lower members beingprolonged above and beyond the ends of said channels, with formation ofa solid pivotsupporting portion, whereby an electric conductor receivedwithin the channeled portions of the two members may be led below theprolonged pivot-supporting ends of said channeled members, where saidconductor passes from the channel of one member to the channel of theother member.

In testimony that I claim the foregoing as my invention, I have hereuntosigned my name this 23d day of September, A. D

ARTHUR W. BROWNE. In the presence of- ALBERT A. Smvnns, GEORGE H.BROWNE.
